The name magnesium originates from the Greek word for locations related to the tribe of the Magnetes, either a district in Thessaly called Magnesia [52] or Magnesia ad Sipylum, now in Turkey. [53] It is related to magnetite and manganese, which also originated from this area, and required differentiation as separate substances.
The magnesium monohydride molecule is a simple diatomic molecule with a magnesium atom bonded to a hydrogen atom. The distance between hydrogen and magnesium atoms is 1.7297Å. [32] The ground state of magnesium monohydride is X 2 Σ +. [1] Due to the simple structure the symmetry point group of the molecule is C ∞v. [32]
The magnesium argide ion, MgAr + is an ion composed of one ionised magnesium atom, Mg + and an argon atom. It is important in inductively coupled plasma mass spectrometry and in the study of the field around the magnesium ion. [ 1 ]
Magnesium oxide is the end product of the thermal decomposition of some magnesium compounds and is usually prepared by igniting carbonates or hydroxides. Magnesium hydroxide is a strong electrolyte, which can be obtained by the reaction of a soluble magnesium salt and sodium hydroxide.
Magnox (alloy), whose name is an abbreviation for "magnesium non-oxidizing", is 99% magnesium and 1% aluminium, and is used in the cladding of fuel rods in magnox nuclear power reactors. Magnesium alloys are referred to by short codes (defined in ASTM B275) which denote approximate chemical compositions by weight. For example, AS41 has 4% ...
The magnesium compound magnesium sulfate was first discovered in 1618 by a farmer at Epsom in England. Strontium carbonate was discovered in minerals in the Scottish village of Strontian in 1790. The last element is the least abundant: radioactive radium , which was extracted from uraninite in 1898.
the hydrogenation of magnesium anthracene under mild conditions: [5] Mg(anthracene) + H 2 → MgH 2. the reaction of diethylmagnesium with lithium aluminium hydride [6] product of complexed MgH 2 e.g. MgH 2.THF by the reaction of phenylsilane and dibutyl magnesium in ether or hydrocarbon solvents in the presence of THF or TMEDA as ligand.

Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It has an empirical formula of MgO and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding .
